AIM:Configuration of Static Routing Desk and Routing Info Protocol (RIP) utilizing Packet Tracer.
THEORY:
Router: Community router could be outlined as community machine with interfaces a number of networks whose process is to repeat packets from one community to a different usingthe routing tables saved within the reminiscence. Router makes use of one or extra routing protocols( i.e RIP,BGP, OSPF. Routers additionally settle for routes that are configured manually by a community administrator. These routes could be known as as static routes. The router use this information to make routing tables. The community router will then use these routing desk to make choices about which packets to repeat to which of its interfaces. This course of is named routing.
Router has 4 elements: enter ports, output ports, the routing processor and the switching cloth.
a) Enter port performs the bodily and knowledge hyperlink layer capabilities of the router. The bits are constructed from the acquired sign, packet is de-capsulated from the body, errors are detected and corrected. The packet is able to be forwarded by the community layer. Enter ports has buffers (queues) to carry the packets earlier than they’re directed to the switching cloth.
b) An output port performs the identical operate because the enter port, however within the reverse order.
c) Routing Processor: The vacation spot tackle is used to seek out the tackle of the subsequent hop. Routing processor searches routing tables.
Switching Materials: It strikes the packet from the enter queue to the output queue. Prior to now, reminiscence of the pc or a bus was used as the switching cloth. The only sort of switching cloth is the crossbar change which connects n inputs to n outputs in a grid, utilizing electronics micro-switches at every cross level.
